After an accident upgrade my 3g iphone to 3.1, I have read one the post in here and followed the guide to down grade to 3.0 then JB the iphone with 3.0 and restored with the custom 3.1, everything went thru fine and I sucessfully JB the phone. Added the ultrasnow url from cydia and installed the ultrasnow to unlock the phone. but when the device reboot, I have searching ... for awhile then it display NO Service ...
I did reset the Network, turn oFF the 3G, place my SIM to a tmobile phone and make few calls then put back to the iphone but no luck for the unlock. Please help

It's not that simple. Your baseband is permanently updated. 3.1 for iPhone 3G's has been jailbroken but the new baseband has not been unlocked and it is unknown if it will ever be unlocked. Read about it here

Thank you GIRLLLLLLLLLLLLLLLLL for the good description.
I did the same mistake vietkool did, upgrading to 3.1 over iTunes, and spent the last day trying to find a solution because of million of people claiming that they know how to do it.
Your description makes it clear that there is currently no way of fixing this (unlocking the iPhone after iTunes 3.1 upgrade).
Could you plese post if the fix for this poblem is found.
Thank you once more

upgrading a 3gs to 3.1 could have been the most expensive mistake you've made all year...
700 dollar iPod touch now...
the dev team MOST LIKELY will never release a 3.1 unlock... maybe its time to start looking for turbosims compatible with 3.1?The only thing I ask in return for helping, is that you click the thanks button, Thanks!

I'm quite new at this. Could you explain what turbosims are?

It a hardware thing. It goes over the sim to trick the phone to see the sim ( in the US as At&t) as a normal carrier sim.

Best way to keep up with any info is the main page here or checking on the dev teams website. All of us here are more than willing to offer help but we also get the same info from here and there. I have the main page as one of my daily sites to check and then hit the forums.
